Saginaw County District Judge Terry L. Clark signed the warrant charging Allen about 11:15 a.m. Friday, Jan. 17, and he is scheduled to arraign Allen at 1:30 p.m. Friday.

Felony murder carries a mandatory penalty of life in prison without the possibility of parole. The charge means somebody was killed during the commission of a specified felony, and Allen's arrest warrant alleges he killed Vasquez “while in the perpetration or attempted perpetration of child abuse in the first-degree.”

Boyd said an autopsy report shows "foul play” was involved in the boy's death.

In relation to the child abuse charge, which carries a maximum penalty of life in prison with parole, Allen's arrest warrant alleges he “did knowingly or intentionally cause serious physical harm” to Vasquez.

Police on Jan. 8 arrested Allen on allegations he violated his probation by having drugs and drug paraphernalia at his home. The warrant alleging the violation was not entered until Jan. 10, meaning authorities did not know of the violation until after the alleged incident.

Allen was on probation for attempted possessing with intent to deliver marijuana in July 2012 in Saginaw and possessing marijuana in January 2011 in Saginaw. He pleaded guilty Jan. 14 to eight probation violations and is scheduled for sentencing on Feb. 10.
